MACHINE FOR FORMING BLANK HOOKS FOR WIRE BALE-TIES.

SPECIFICATION formingpart of Letters Patent No. 262,796, dated August15, 1882.

Application filed March 24,1882. (No model.)

To all whom it may concern:

Be it known that I, EDWIN S. LENOX, of the city and county ofIVorcester, and Commonwealth of Massachusetts, have invented certain newand useful Improvements in Machines for Forming the Blank Hooks of WireBale-Ties; and I do hereby declare that the following is a full, clear,and exact description of the same, reference being had to theaccompanyingdrawings, forming a part of this specification, and in whichFigure 1 represents a top view of my mathe wire is introduced. Fig. 2represents a top view of my machine, showing the position of the partsafter the blank hook is formed. Fig. 3 represents a front view of mymachine has been begun. Fig. 4 represents a side view of my machineafter the operation of forming the blank hook is completed; and Fig. 5represents a side view of a bale-tie blank enlarged.

The particular class of wire bale-tie the blank of which is made by myinvention is that known as a cross-head, and the machine may be thusbriefly described.

Upon a suitable standard is mounted a table on which may be set a topplate, forming the bed over which the wire is to pass, its course beingregulated by suitable adjustable guides, which also serve to preventlateral movement of the wire during the operation of forming the blank.Ina sleeve formed on the inside of the table is carried a vertical shaftrotated by means of a treadle drawing on a belt secured to a pulley onsaid shaft, which is turned to its normal position by a spring connectedtherewith by a belt suitably conducted. On the upper end of thisvertical shaft, which is on a level with the top plate, if used, areplaced two pegs at right angles, or nearly so, to the line of the wirepassing between them. To the table is pivoted a lever having also twopegs arranged in the line of its axis and, consequently, at an angle tothe wire, which also passes between these. By pressing down the treadlethe vertical shaft is turned half a revolution, the pegs thereon formingthe bottom of the loop-that is, the hook. The pivoted lever is thenturned, thus bending back the wire, the length of the return-piece beingdetermined by an adjustable gage secured to the table.

To enable those skilled in the art to which my invention belongs to makeand use the same, I will proceed to describe it more in detail.

In the drawings, the partAis the standard, of any suitable size andshape, upon which is mounted and secured in any approved way a table, B,preferably of the shape shown, on this being usually placed a top-plate,B, on which are again set guides O O, adjusted and secured in positionby set-screws c c, the space between them being the path along which thewire is passed to the operating mechanism.

The part D is a short vertical shaft carried in a sleeve, B projectingfrom the under side of the table A, and having on its upper end, whichis flush with the upper surface of plate B, pegs d d, between which thewire passes.

D is a pulley mounted on D, to which is attached one end of a belt, E,passing over sheaves E E (carried respectively in suitable brackets, c,and on the standard A.) and having its other end connected to a treadle,F, pivoted to the standard. A belt, G, secured to the pulley D, passesover a sheave, G, carried in brackets g, and is attached to a spring, H,fastened to the stand. (See Fig. 3.)

The part K is a bent lever, pivoted where shown to the table B, andcarrying on its upper surface, which is on a level with the plate B,pegs 70 70, between which the wire is pushed, one being at thepivot-point and the other outside it, L being a gage to adjust thelength of the wire, secured on the table in the desired position byajam-nut, Z, passing through a slot, 1), in same.

The operation of my invention is as follows: The parts being in theposition shown in Figs. 1 and 3, the wire is introduced between the pegsd d and 70 la, being pushed through until the end meets the gage L, thedistance between this gage and the pin 70 regulating the length of thereturn-piece to be subsequently twisted with the main strand by otherapparatus. The treadle F is then pressed down, thus drawing on the beltE, and through it imparting a full half-revolution to the shaft D, andwith it the pegs d d, which hold the wire and bend it into a hook toform the inner end of the tie-blank, as shown in Fig. 2, the guides O (Jpreventing any lateral movement of the wire. The lever K is then turnedaround to the position shown in Fig. 4, the pegs 7H0 holding the Wirebetween .them and bending it back, so as to form a rounded end on thetie and complete the blank shown in Fig. 5. The blank being removed andthe treadle released the action of the spring H draws the belt G andgives to the shaft D half a turn in the reverse direction, thusrestoring it to its first position ready for use.

I disclaim the invention described in the Letters Patent granted to U.Van Derzee, November 14:, 187 6, and marked No. 184,448. v

Having described my improvements in machines forformingthe blank hooksof wire baleties, what I claim therein as new and of my invention, anddesire to secure by Letters Patent, is-

1. In a wire-bale-tie-blank-formin g machine, the combination of arevolving shaft carrying pegs which hold the wire and, when turned,

bend it into a hook or S shape, and a lever also carrying pegs, betweenwhich the wire is held, and serving, when turned, to bend back the endof the tie, all substantially as described and shown.

2. The combination, with the revolving shaft D, provided with pegs d 61upon its upper end for bending the wire, of the guides O O, forpreventing the lateral movement of the wire during such bendingoperation, all substantially as described, and for the purposes setforth.

3. The combination, with the revolving shaft and lever, providedrespectively with pins for bending the wire,of adjustable gage L, allsubstantially as shown and described.
